SVS Series - Single-Phase
Servo Electronic AC Voltage Stabilizers -
1 to 100kVA

Suitable for 95% of all applications, SVS Servo Electronic Stabilisers  not only guard against voltage fluctuations they also offer protection against all too common harmful high-energy surges, transients and voltage spikes.

Remastered to meet the demands of today’s modern age, our latest generation SVS Series models deliver a step-less automated regulation of the incoming utility mains supply.

Offered as two ranges, in ratings from 1 to 100 kVA, H Series models support international 220 to 240 Volt mains supplies and L Series models support US-Style utility supplies of 100 to 127 volts.

Optional Features
available include:

Outdoor IP54 Enclosure (-IP54)
Stabiliser presented in endurable IP54 (BS / EN 60529) / NEMA 3 free-standing steel cubicles suitable for external use, or more challenging internal environments
Input Isolating Transformer (-PC)
Through the integration of a shielded isolation transformer, provides enhanced spike & electrical noise (Common Mode: 120db @ 100khz & Normal Mode Noise: 60db @ 100khz) suppression and neutral ground bonding. Delivers what is commonly referred to as a ‘CLEAN’ supply
Full Manual Maintenance Bypass (-MBS)
While many Customers, following traditional wisdom, prefer to install a bypass facility that is external to the Stabilizer/Conditioner, where requested models can be fitted with an integrated traditional ‘Break Before Make’ bypass facility. This feature is handy when performing remedial works or deep maintenance on the system.
Digital Power Metering (-DPM)
Microprocessor-based output digital power metering, with event logging – monitoring V, A, W, VAR, PF, W Hrs & VAR Hrs and the offering  RS-485, Modbus RTU, Modbus ASCII, Jbus Protocol interface

Alternative Paint Colour Finish – customer to specify
Output Circuit Breaker (-OCB)
An Output Circuit Breaker to protect the load  against overload and short circuit
UL Recognised Component (-URC)
For 
applications where UL compliance is required, the Stabilizer / Conditioner can be supplied with UL approved Input Breakers and Output Contactors / Breakers, so that the client can obtain on-site UL approval of the installation
